Frequently asked questions
Can I use these internal SSDs in my PS5 instead of the DATO external drive?
Yes, several listed drives support PS5 expansion. The Fanxiang S660, S880, Ediloca EN855, Fikwot FN955, and Ediloca EN705 are all compatible with PS5 gaming. You must ensure the drive fits the M.2 2280 slot. Internal drives offer faster load times than external USB connections for console storage.
Do any of these alternatives include a heatsink for thermal management?
Some models feature built-in cooling solutions. The Fanxiang S660 and Ediloca EN855 both come with integrated heatsinks to help manage operating temperatures. The DATO also uses graphene cooling. Other drives like the Fanxiang S880 and Fikwot FN955 do not include heatsinks in their standard configuration, relying on your system airflow.
Which alternative offers the best performance for PC gaming?
The Fanxiang S880 provides high sequential read speeds of up to 7,300MB/s. This makes it suitable for users seeking peak performance on PCs and PS5. The Fikwot FN955 and Ediloca EN855 also utilize PCIe Gen4 interfaces for fast data transfers. These speeds exceed the 1,600MB/s limit of the DATO's USB connection.
Is there a compact option similar to the BUFFALO drive?
The BUFFALO 2TB Portable SSD is notably compact at 0.91 by 0.43 inches and weighs just 0.6 ounces. It is designed for easy portability alongside PS5 storage needs. The DATO is larger at 1.81 by 0.65 inches. If you prioritize a small footprint, the BUFFALO model is the most streamlined choice listed.
Do any of these drives use DRAM cache for better consistency?
The Ediloca EN855 is the only listed drive with DRAM cache. DRAM cache helps manage data flow more efficiently, which can improve sustained write speeds. Most other alternatives, including the Fanxiang and Fikwot models, rely on SLC caching instead. If you require hardware-level memory buffering, the Ediloca EN855 is your best option.
Are these internal SSDs compatible with laptops?
Yes, several internal drives support laptop upgrades. The Fikwot FN955 and Ediloca EN705 explicitly list laptop compatibility. They use the standard M.2 2280 form factor. You must verify that your laptop has an available M.2 slot and supports PCIe Gen4 speeds for optimal performance. The DATO and BUFFALO are external and do not fit inside laptops.
What is the difference between the two Ediloca 2TB drives?
The Ediloca EN855 includes a heatsink and DRAM cache for enhanced thermal and performance management. The Ediloca EN705 is a value-focused model with SLC caching and no included heatsink. Both are PCIe Gen4 M.2 2280 drives compatible with PS5 and PCs. Choose the EN855 for cooling and caching, or the EN705 for basic storage needs.
